8 Claims.

My invention relates to improvements in horse shoes, particularly those of the type which have a metal shoe-shaped insert surrounded with rubher, and the object of the invention is to devise such a shoe which will be equally adaptable for use under varying climatic conditions so that it may be used throughout the year.

In practice, it is found that rubber encased horse shoes on account of their anti-slipping characteristics, while reasonably suitable for surefooted and strong legged horses are not suitable for animals with weak fetlock joints and therefore susceptible to knuckling over. When such a horse puts its foot down on the road surface, there is no slip of the rubber encased shoe on the road with the result that knuckling over occurs. The present invention has for an object the curing of this disadvantage.

Furthermore, in the case of all rubber cove-red horse shoes, their use is restricted to climatic conditions where no ice exists on the road, and they are accordingly not suitable under winter conditions when they must be replaced by metal shoes. A rubber encased shoe constructed according to my invention is equally susceptible to use in winter and summer by the mere changing of metal calks as hereinafter described.

With the above and other objects in View which will hereinafter appear as the specification proceeds, my invention cosists in its preferred form of the construction all as hereinafter described and illustrated in the accompanying drawings, in which:-

Fig. 1 represents an inverted plan view of a 2 shoe constructed according to my invention with metal calks applied thereto such as are suitable for use under climatic conditions where no ice or hardened snow is on the road.

Fig. 2 is a side view of the shoe illustrated in 4 Fig. 1.

Fig. 3 is a vertical section taken through a shoe illustrated in Fig. 1 showing a metal calk in elevation.

Fig. 4 is a detail in inverted plan of the forward part or toe of the shoe illustrated in Fig. 1 showing the construction of the rubber toe calk portion with the-metal calks removed. 1

Fig. 5 is an inverted plan view of the metal shoe-shaped insert adapted to be encased by the rubber.

Fig. 6 is an inverted plan view of the shoe illustrated in Fig. 1 showing it adapted to receive metal toe calks suitable for use on ice and such calks in place.

erably tapered as are the orifices although, if desired, the shanks might be threaded Fig. 7 is a side View of the construction of shoe and metal calks illustrated in Fig. 6, and

Fig. 3 is a detail in inverted plan showing the portion of the shoe adapted to receive the metal toe calks illustrated in Figs. 6 and 7 but with such calks removed.

Like characters of reference indicate corresponding parts in the difierent views.

According to the preferred form of my invention, I employ in the construction of my shoe a shoe-shaped metal insert [including a toe clip 2 and nail orifices 3, said insert including the toe clip being encased in a resilient rubber encasement 4 in which on the road engaging face are formed rubber heel calks 5 and a rubber toe calk 6 preferably joined together by rubber ribs i which are disposed in the vicinity of the inner marginal edge of the encasement leaving recessed portions 8 exteriorly thereof between each rubber heel calk and the rubber toe calk. The recessed portions 8 have nail receiving indentures 9 adapted to register with the nail orifices 3 in the metal insert.

As will be observed upon reference to Figs. 2,

3, 5, and 6, the rubber encasement tapers from heel to toe of the shoe.

The rubber toe calk 5 has orifices Ill extending vertically therethrough which register with orifices Ii in the toe portion of the encasement 4 above the insert I, and said insert has register ing orifices I2 therethrough which also register with the orifices II] and I I. Corresponding orifices it, I I, and 52 are spaced from the longitudinal centre line of the shoe, and the orifices It are enlarged at I3 to receive the metal anti-knuckling over toe calks I4 which have shanks I5 inserted through the orifices I0, II and I2.

In order to secure the metal anti-knuckling over toe calks I4 in place, the shanks are pref- I2 in the insert,

into the orifices I2.

Surrounding the orifices I2 in the insert i are annular bosses I6 having rearwardly extending ribs I'I', both forged or otherwise formed on the insert for the purpose of reinforcing the same. Initially the depth of the metal anti-knuckling over toe calks I4 is such that they protrude below the road engaging surface of the rubber toe calk 6 as illustrated in Figs. 2 and 3 of the drawings, but in use as the steel calks wear faster than the rubber they wear down substantially flush with the rubber, and they are protected. from further excessive wear by such rubber. The effect of such steel calks applied to the rubber calk is to permit a certain amount of slipof the shoe on the pavement when the horse puts the toe of a shoe thereon thus obviating the tendency of a horse to knuckle over as occurs with shoes in which the road engaging surface is all rubber. As the horse subsequently puts a foot firmly on the pavement further slipping is prevented by the rubber calks and ribs.

With metal anti-knuckling over calks l4 fitted to the rubber encased shoe, the shoe is suitable for use during the seasons of the year when no ice or hard snow is present on the roads but when the latter condition prevails the metal antiknuckling over calks 14 are replaced by metal frost calks i8 having chisel-like road engaging edges 19. The frost calks [8 have shanks 2i! identical to the shanks I5 of the metal anti-knuckling over calks l4, and. thus they are inserted into the rubber toe calk 6 in exactly the same manner. However, as the rubber toe calk 6 is originally formed with rubber completely surrounding the indentures l3 which receive the metal antiknuckling over calks I4, it is necessary for the shoesmith, when substituting the metal antiknuckling over frost calks 18 for the calks M, to cut away the outer sides of the walls of the indentures I3 to receive the frost calks I8 as is clearly illustrated at 2| in Figs. 6 and 8 of the drawings. Otherwise no change has to be made in the rubber encased shoe which can remain on the horse until it is completely worn out irrespective of what climatic conditions may be met with.

From the above description, it will be apparent that I have devised a rubber encased shoe which will be capable of being used throughout the year and which will not have to be replaced by a steel shoe when icy road conditions are met with as occurs with rubber encased shoes unprovided with my improvement. Consequently, my shoe effects a considerable economy in time and expense of re-shoeing horses as well as preventing knuekling over with horses having weak fetlock joints or which are prone to this characteristic.

What I claim as my invention is:

1. A horse shoe comprising a shoe-shaped meta1 insert with orifices through its toe portion, each disposed in spaced relation to the longitudinal centre line of the insert, a resilient rubber shoe-shaped encasement surrounding the insert and having orifices therethrough registering with the orificesin the insert, the lower ends of such orifices being of increased diameter to constitute shoulders in such orifices, and shouldered metal calks inserted into the orifices in the encasement and insert with their lower edges at least substantially fiush with the road engaging surface of the rubber encasement and their shoulders abutting the shoulders in the orifices thereof.

2. In a horse shoe as claimed in claim 1, the metal calks comprising enlarged road engaging head portions and reduced tapered shanks extending up through the orifices in the rubber encasement and insert.

3. In a horse shoe as claimed in claim 1, bosses formed on the insert and surrounding the orifices therethrough, and ribs formed on the inserts and extending rearwardly thereon from the bosses.

4. A horse shoe comprising a shoe-shaped meta1 insert, a surrounding shoe-shaped encasement of resilient rubber including depending toe and heel calks formed thereon, and metal calk means disposed in .the road engaging surface of the rubber toe calk adapted to contact the road surface and permit the rubber toe calk slipping thereon a limited extent prior toexerting its anti-slipping characteristics, and means extending up through the rubber toe calk and rubber encasement for securing the metal calk means to the insert.

5. A horse shoe comprising a shoe-shaped meta1 insert, a surrounding shoe-shaped encasement,
